Introduction to Privileged Access Workstations

Over the past few years, Microsoft has invested heavily in protecting identities. We now have phishing-resistant authentication, Authentication Strengths, Privileged Identity Management (PIM), Conditional Access, Identity Protection and many other capabilities that help reduce the risk of account compromise.

Yet despite these advances, one area is still frequently overlooked.

The device used to perform privileged administration.

As identity has become the new security perimeter, the workstation from which privileged identities are used has become just as important as the authentication methods protecting them. It doesn’t matter how strong your authentication is if the device itself cannot be trusted.

This is where Privileged Access Workstations (PAWs) enter the conversation.

More Than Just Another Laptop

One of the biggest misconceptions surrounding PAWs is that they are simply dedicated laptops for administrators.

They are much more than that.

A Privileged Access Workstation is a security control designed to reduce the attack surface surrounding privileged identities. By separating administrative activities from everyday productivity tasks such as email, web browsing, document editing and collaboration, organisations create a stronger trust boundary around their most valuable accounts.

The objective isn’t to make compromise impossible.

The objective is to make compromise significantly more difficult.

Why This Matters

Modern attacks increasingly target identities rather than infrastructure.

An attacker doesn’t necessarily need to exploit a server vulnerability if they can compromise a privileged administrator’s workstation.

Once an attacker gains access to that endpoint, they may be able to steal authentication tokens, capture browser sessions, exploit local vulnerabilities or simply wait for an administrator to activate a privileged role using Privileged Identity Management.

The workstation becomes part of the attack surface.

Protecting privileged identities therefore requires more than strong authentication alone.

Security Is About Layers

Many organisations have already invested in modern identity security.

They have deployed passkeys or FIDO2 security keys.

They have implemented Conditional Access.

They use Privileged Identity Management to minimise standing privilege.

They monitor risky sign-ins and risky users.

These are all essential controls.

However, they each address different parts of the identity lifecycle.

A Privileged Access Workstation adds another layer by protecting the environment from which privileged administration takes place.

Like every other security control, it should be considered as part of a defence-in-depth strategy rather than viewed in isolation.

There Is No Universal PAW

Another common misconception is that every administrator should have a dedicated physical workstation.

In reality, the answer is rarely that simple.

Some organisations may decide that only their highest assurance identities require dedicated physical PAWs.

Others may use Windows 365 Cloud PCs.

Some may implement Azure Virtual Desktop administrative environments for operational teams.

Others may determine that highly hardened managed devices provide an acceptable balance between security, operational complexity and cost.

None of these decisions are inherently right or wrong.

They should be driven by organisational risk, business requirements and the level of assurance required for the identities involved.

The Goal of This Series

This series isn’t intended to provide a single blueprint that every organisation should follow.

Every organisation has different risks, different budgets and different operational requirements.

Instead, the goal is to explore the architectural decisions behind Privileged Access Workstations, explain the options available and discuss where each approach fits within a modern Microsoft security strategy.

Throughout the series we’ll explore:

• What a Privileged Access Workstation actually is
• When a PAW is justified
• Physical versus virtual PAWs
• Windows 365 as a dedicated administrative platform
• Azure Virtual Desktop for shared administration
• Hardening a modern PAW using Microsoft technologies
• Building a Trust Level-driven administrative strategy

The intention isn’t to tell you there is only one correct answer.

It’s to help you make informed architectural decisions that align with your own organisation’s security objectives.

What’s Next?

In the first article of the series we’ll answer the question that usually starts every conversation:

What is a Privileged Access Workstation, and why does it matter?

From there we’ll build towards designing modern administrative environments that balance security, usability and operational practicality.

Whether you’re responsible for a handful of privileged administrators or an enterprise-scale identity platform, the principles remain the same.

Protect the identities that matter most by ensuring the environments they operate from deserve the same level of trust.
